MOCVD Technician

As a MOCVD Technician, you will support the operation, maintenance, and reliability of epitaxy systems used in semiconductor manufacturing.

This is a hands-on technical role focused on maintaining complex gas, vacuum, and reactor systems that enable the production of high-performance semiconductor laser materials. You will work closely with engineering and production teams to ensure safe, stable, and efficient operation of critical manufacturing equipment.

Key Responsibilities

• Equipment Maintenance & Reliability
  • Perform preventive and corrective maintenance on MOCVD reactors and associated infrastructure (gas supply, abatement, vacuum systems)
  • Support maintenance of vacuum pumps and gas systems
• Troubleshooting & Repairs
  • Troubleshoot mechanical, electrical, and process-related issues to ensure system uptime
  • Replace and maintain components such as filters, piping, and gas handling systems
• Safety & Operations
  • Safely handle and exchange pressurized gas cylinders, following strict safety protocols
• Monitoring & Process Stability
  • Monitor and interpret system data and logs for fault diagnosis (e.g. SPC)
  • Ensure equipment availability and process stability in a production environment
  • Document maintenance and service activities in line with quality standards
• Testing & Systems Support
  • Support the setup and maintenance of measurement and testing systems (e.g. wafer characterisation or similar diagnostic equipment)
  • Work with control systems (PLC-based) to identify and resolve operational issues

 

Qualifications

• Completed technical training, apprenticeship, or equivalent in Mechatronics, Electronics, Automation, Industrial Mechanics, or a related field
• ~3+ years of hands-on technical experience (or strong apprenticeship background)
• Experience in semiconductor manufacturing, chemical processing, gas systems, vacuum systems, or similar industrial environments is a plus, but not required.

Skills & Other Requirements

• Understanding of basic physics and technical systems (pressure, gas flow, electrical fundamentals)
• Ability to read and interpret electrical schematics and technical diagrams
• Experience with maintenance and troubleshooting of industrial equipment
• Strong awareness of safety protocols, particularly in regulated or hazardous environments
• Ability to work in a cleanroom and safety-critical environment, including use of respiratory protection equipment (training provided)
• German working proficiency required and English language skills is a plus
